for example the stone hatchet. I would love to blacklist the stone tools and stuff because I'm making a RP server and this is something I want the player to buy with RP through a vendor.

{
"Simple Mode (disables advance blueprint management options)": true,
"Update players on permission change (automatically updates a players BPs when their permissions change)": true,
"Blacklist (items from being automatically learnt)": [
"stonehatchet"
],
"DefaultBPs (Blueprints to be automatically learnt)": [],
"Assign custom BP unlocks to various perms (permission, BP List": {
"customperm1": [
"rock"
],
"customperm2": [
"torch"
]
},
"Advanced Blueprint Management Options": {}
}

I'd recommend using the advanced mode and then you can disable BPs from being researched And from being default. But you will also need to use something like a tech tree plug-in or crafting controller to also block those methods as well.

would be worth watching this

Hey!
Is there a solution to this?
I'm trying to remove all default BPs to stop them from appearing in the crafting menu.
I've added all items and set "defaultBP" to false for all items, but vanilla defaultBPs still appear in the crafting menu.
